Scientists can now predict the arrival of blooms of poisonous jellyfish by monitoring trade winds.
Irukandi box jellyfish are invisible in the water and very small. Their stings are extremely painful, and can be fatal. They are found throughout the oceans, but are most common in tropical waters where they may appear suddenly in mass.
Previously, the arrival of the jellyfish was unpredictable, but a study of wind patterns in Australia and database of stings revealed that the arrival of jellyfish coincided with a drop of the south-east trade winds.
